WILLIAM L. GIBSON AND JAMES V. ROYAL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNORS TO THE ROYAL GAS HEATING COMPANY, OF CAMDEN, NEW JERSEY, A CORPORATION OF NEW JERSEY.

GAS-HEATER.

Patented Dec. 3, 1907.

Application filed August 17, 1906. Serial No. 331013.

To all whom it may concern:

Be it known that we, WILLIAM L. GIBsoN and JAMES V. ROYAL, citizens of the United States, residing in Philadelphia, Pennsyl-' gas or other form of heater with a vapor generating apparatus so constructed that the evaporation of water from the same may be regulated as desired; another object of the invention being to so arrange the said vapor generating apparatus that it may be conveniently refilled whenever this is necessary.

We further desire to provide a novel combination of terra cotta or equivalent casting, vapor generator, and an inclosing guard or screen for the same, in connection with a gas burner; the whole being so arranged as to present an attractive and ornamental ap pearance.

It is also wished to provide a gas heater, having the above noted characteristics ,with means for deflecting the hot air rising from the burner so that this shall be distributed in outwardly flowing currents.

These objects we attain as hereinafter set forth, reference being had to the accompanying drawings, in which 4 Figure 1, is a vertical section of one form of a gas heater embodying our invention; Fig. 2, is a horizontal section taken on the line 22, Fig. 1; Fig. 3, is a fragmentary vertical section of the vapor generator; Fig. 4, is a front elevation of another form of heater to which our invention may be applied; Fig.

. 5, is a vertical section of the structure shown in Fig. 4; Fig. 6, is an inverted plan view illustrating the means for regulating the supply of heat to the water evaporator, and F 7, is an enlarged vertical section of the vapor generator shown in Figs. 4 and 5.

Referring first to Figs. 1 to 3 inclusive, A represents the hollow base of a gas heater designed with a series of openings c in its sides and also a larger opening in its top surface. Supported upon this base and fixed thereto in any desired and suitable manner are a series of vertically placed perforated or reticulated plates forming a screen or guard arranged in the present instance in the form of an octagon and having at their top an ornamental marble cover B.

While we have shown the plates 1) as arranged in the form of an octagonal body, it will be understood that theymaybe arranged in any other desired manner without departin from our invention.

astened to the underside of the marble top B and, if desired, held in position by dowel pins projecting from the upper edges of the side plates or screens 12, is a downwargly projecting, inverted, conical deflector Carried upon the center of the base A is a burner D, which, in the present instance, is annular in form and supplied with suitable mixtures of air and gas or gas alone through a supply pipe d. This burner is, in the present instance, surrounded by a terra cotta casting E, constructed to simulate a pyramidal body of logs; the casting being open at the top and having a series of elongated triangular openings d extending through the lower portion of its sides into its interior and down the lower portion thereof.

WVithin the screen and resting upon the base A outside of the refractory casting E, is a tripod formed by three poles f from which may be suspended, by means of a chain, the vapor generator F, designed to simulate a well known form of kettle or pot. The construction of this vapor generator is illustrated in Fig. 3, where it will be seen that the water-containing kettle f is surrounded by an outer casingj' in such manner as to leave an air space between the two; there being, in addition, an asbestos or other heat non-conducting lining f 3 upon the interior of the said outer casing.

As shown in Figs. 2 and 8, the lower part of the outer casing f is provided with a valve or damper f which, by means of an arm f and an operating rod f projecting horizontally to the outside of the screen I), may be operated to open or close said valve or damper f 4 and thereby control the passage of heated air into the space between the kettlefand the casing f Extending from the interior container f to the outside of the screen I) is a pipe g, which communicates with a filling vessel g carried in any desired manner upon the outside of said screen, as shown in Figs. 1 and 2.

- -W hen the burner D is in operation, it will be seen that the-gas flames therefrom will rise inside the terra cotta casting and serve to render incandescent particles 6 of shredded asbestos, which we preferably place along the edges of the openings into said casting, so that, particularly when viewed through the screen or guard b, the whole has the appearance of a gypsy log fire; the resemblance, as well as the ornamental effect, being further heightened by the use of the tripod and th vapor generator.

By means of the rod f the rate of evaporation from the container f can be regulated to a nicety, since by shutting the valve or damper f*, the heated air or gas rising from the burner or gas log may be practically cut ofl from the space between the casings f and f and the evaporation of the water in the generator in a great measure prevented or, at least, regulated within desired limits. The upwardly flowing current of hot air and gases of combustion upon striking the conical deflector C, are directed horizontally outward from the heater, so that an eflicient and desirable distribution of the heat is attained. As will be obvious from an inspection of Fig. 1, the filling of the water vessel f is accomplished by pouring water in the outside receptacle g.

It is obvious that our improved means for regulating the evaporation of water from a vessel supported over a heater in order to supply the necessary amount of moisture to the atmosphere of a room, may be applied to other styles of heaters than that illustrated in Figs. 1 and 2. For example, if desired, we may provide a heater of the well known form, as shown in Figs. 4 and 5, with an elongated and ornamental container F, supported horizontally above the top edge of the fire plates. As shown in Fig. 5, liquid is evaporated from this container by the current of hot air and products of combustion rising from the gas logs E, and, as before, the rate of evaporation may be varied by means of a damper of the form shown in Fig. 6. In this instance, the damper consists of a number of plates f all connected together and longitudinally movable by means of an operating rod or handlef, so as to cut off or admit the heated air to the space under the water containing vessel f. As in the case illustrated in Fig. 3, the vessel as shown in Fig. 7, is preferably provided with an inner and outer casing having an air space between them, while openings f are provided in said outer casing F in order to permit of circulation of heated air through the device.

While the casting E is preferably composed of terra cotta, it will be understood that it may, without departing from our invention, be made of porcelain, iron, or other refractory or semi-refractory material.
